The C7 Corvette C7 MRT Street Race Cat Back exhaust has a loud, deep muscle car sound and is handcrafted entirely in corrosion-resistant T304 Stainless Steel. Base systems include T304 polished SS 4" tips and 3" mandrel-bent tubes. A Black Ops tip finish is available for an additional fee (Black Ops is a high-temperature ceramic coating in black matte finish). This system is engineered for the best sound to provide your Corvette with the perfect balance of performance sound in spirited driving - comfortable in highway driving and managed sound at low speed and idle. This exhaust variant has a straight-through design with the loudest exhaust note, versus the stock exhaust. This Cat-Back exhaust will give you improved performance and sound with a minimal drone as well.

For Corvette customers with factory-installed AFM / NPP devices, MRT offers and recommends a simple solution that allows you to upgrade your exhaust system without having to develop a tune to defeat the AFM. For more information on these plates, refer to MRT Part #91X010 or simply add to your shopping cart before checkout. **AFM Plates are required on all automatic C7s or you will throw a check engine code.**

Application: 2014 thru 2019 C7 Corvette 6.2L V8 engine.
Doesn't Fit: Other Corvette models.
